A 4.0 magnitude earthquake shook the San Francisco Bay Area on Monday and viewers who felt the tremor likely had the same reaction as a CBS weatherman Steve Paulson.

The CBS weatherman was in the middle of his forecast when the quake hit.

Paulson jumped when he felt the shaking and grabbed the screen behind him before throwing it back to his colleagues who described the quake as “strong.”

The United States Geological Survey noted that the trembler rattled residents in the Bay region at 6:49 a.m. and was centered near Modoc Avenue east of Mountain View Cemetery in Oakland.

The USGS also said that the quake was followed by several aftershocks; some measuring at 2.4.

The shaking could be felt in downtown San Francisco, along the Peninsula and in the East Bay. Some 4.5 million people in total likely experienced either strong or light shaking depending on their location.

After the quake, tracks for public transportation trains need to be checked for damage and commuters had a bit of delays.
